Calcium carbonate |
The correct answer is 4. Calcium carbonate. The chemical name of marble is calcium carbonate. Marble is primarily composed of calcium carbonate (\(CaCO_3\)), which is a common mineral found in sedimentary rocks. When limestone undergoes metamorphism under conditions of high pressure and temperature, it recrystallizes to form marble. Therefore, marble is essentially a metamorphosed form of limestone, and both limestone and marble share the same chemical composition of calcium carbonate. |
